St. I a'ul, in the county of Decatur-and State of Indiana, have-invented certain new and use.

n ful Improvements in vllIole-Plo'ws; and I do hereby declare that the following is a'fu'll,clear and exact description ofthe same, reference being had to the accompanying drawings, and.

tothe letters of reference marked thereon.4 The nature of my invention consists in constructing and arrangingthe several parts of a mole-plow substantially in4 the manner hore- 'inafter described.`

In the drawings, rigureiis ai side elevation,

Fig. 2..is an Aenlarged detached section ofthe slot and clev'is.v n

, To enable those skilled in the art to fully un- .derstand and construct :my invention, I will proceed to describe its`construction andfoper;

ation. ,l

The beam A is supported atits forward end The cutter B is secured to the about two inches from thel'owier ,end of the cutler andtwo inches from the back edge of the'f cutter, one-inch wide, andis extended upward as far asfmay be desired. vThe clevis c is formed of twostra'ps of iron of equal length, Width, landthickness, with jthereaif end of each bent in such a manner-as to' bring them close together, where-they are perforated to receive the connectinglink `from the mole; or itA may be formed by 'bendinga strap of iron and beati-ngv it together at the rear'end, as described, leav'-` y ingthe cleviswide enough to slip loosely onthe' cutter. -The boltz passes through thleffront' f ends of 'thecleviscan'd throughthe slote. `The @levis is boltedfloosely tol admitof its being .slidu'p or down o ntheback part, Eef-themes "ter B.- (Showniin Fig. 2.

f1;y is of; an oblong oval shape, and is loose] y'connected to the cle'vis c at Ib, forthedouble purpose of allowing the plowv to be turnedt the; right onleft without breaking or in any way injuring the drain, and to admit of either end of the clevisl c being tippedV up or dow-n, the bolt'a forming a fulcrum'. The screw-rod J 'passes downthrough the beam in the rear of the cutters and '.is provided with ascrew, S, at .its top. This 'screw should be cut the same length of the slot ein the cutter B, to, allow the- .olevisc to'be raised or lowered from oneend Ixof the slot to-the other. .The lower end ofthe jf' #Be it known-that I, SAMUnLF-QJONES, of'

screw-mdd' is secured 'to the clevis c by the bolt a., Thenu'tmiis put on the screw-rod J between theb'ea'm-A and guardi?, and is-held in placeby said guard. 4 nut m is diminished, and is passed Vup through thesguard l? at r to protect the screw from injury by coming infcontact with the guard".i The nutm' is provided with arms an', by which it.

can be easily turned. The stationary roller D supports the rear end of the beam and closes i the opening made/by the cutter on the surface of the ground.

The operationof the machine is 'as followsz' The object is to adj ust the mole. only-when themachine is in motion. Thus, as` the plow .is drawn'forward, the operator, by means of the armed nut m, raises or lowers the screwuod J, the 'lower end of which is looselyconnec't'ed to the clevis e bythe bolt d; N ow, the ralsingor loweringfof the screw-rod J produ-cesafulcrum motion in the clevis c between the bearings at t' and b,.thus admitting the clevis to be gradually slidup Aor down on. the back piece, F, of the cutter B fromoneend of slot-e to the other, or hold it atauy point along said line 0f travel. The mole E, being loosely connected to .the rear Vend'of the clevis,'must of necessity follow the ,elevation or depression of the clevis c, thus enabling the operator to run the drain level independent of the unevenness .of the ground.; Thus while the plow is passing over alow spot l o f ground the mold can beraised to the top of n the slot in the cut-ter, and,notwithstanding the cutter is as. deep in the ground as when on high land, the mole is elevated vnearer the surface of the ground and is running oua level with the .drainmade in higher land. The mole following mg use. mais man df-teinte cutter nas passed, cannot V fail' to Aeifectually vclose the "opening` entirely inthe rear Yof the cutt-'enandnort formmade lbythe cutter, leaving the eartharouud 'the drain as firm and compact as'if the cutter had not passed through. j .The plow should alwaysbe-started at'tlie outlet, where the drain empties, and as it nears the termination. ofthe drain the molev is gradually raised` tothe top ofthe slot. Then the plow is'easily taken from the ground and moved toanother place.
